Pros: Great isolation, sturdy construction, decent bass
Cons: Mids and highs are average; warm bass seems to carry this IEM through
The Shure SE115 is a decent choice in the $70-80 range but no more. Great isolation, very sturdy wires and the ability to add accessories is one of the staples of all Shure models.
This model features warm bass smooth mids but a roll off in the high end so clarity might be a bit of an issue.
However at $80 you can surely find a better sounding IEM such as the HiFiMan RE0.
